Palladium‐Catalyzed Carbamoyl‐Carbamoylation/ Carboxylation/Thioesterification of Alkene‐Tethered Carbamoyl Chlorides Using Mo(CO)6 as the Carbonyl Source

We reported a palladium‐catalyzed carbamoyl‐carbamoylation/carboxylation/thioesterification of alkene‐tethered carbamoyl chlorides using Mo(CO)6 as the carbonyl source. The reactions were typically performed with good functional group compatibility and tolerated different nucleophiles (amines, alcohols, phenols, thiols and water), which provided a new access to amidated/esterificated/thioesterificated/carboxylated oxindoles or lactams bearing an all‐carbon quaternary stereocenter under CO gas‐free conditions. Furthermore, natural product mutation and divergent late‐stage derivatization are the important practical features.
